Subject: [SDL] [patch] sdl glscale backend

To use it, patch your SDL source tree, compile, install and then set the
environment variable SDL_VIDEODRIVER :
export SDL_VIDEODRIVER=glscale        
It scales the picture by a factor 2 by default, but you can set your own
window size using the two env variables SDL_VIDEODRIVER_GLSCALE_X and   
SDL_VIDEODRIVER_GLSCALE_Y.

This latest version avoids pixel copy/conversion most of the time, so
it's faster than the previous one (most games are playable even on my
radeon 7000 card with the free dri drivers :)

The patch is there :

Comment 2 Sam Lantinga 2006-06-21 04:10:29 UTC 
Stephane mentioned this is out of date, and it might be obsoleted by SDL 1.3.  Moved to 1.3 so we can review it once the video drivers are rewritten.
Comment 3 Ryan C. Gordon 2007-07-03 03:02:40 UTC 
I'm closing this as WONTFIX since it doesn't really apply to 1.3 now. Please reopen if this is incorrect.
